ASRock X370 Killer SLI/ac (Our Review)

Overall Assessment

With the X370 Killer SLI/ac, ASRock has once again provided the market with a motherboard that does everything and more.

From the hardware to the presentation, this is a motherboard that packs a punch and is loaded to the brim with useful features.

Hardware and Storage

As the name suggests, the ASRock X370 Killer SLI/ac comes equipped with 802.11ac Wi-Fi. 

This was also implemented in the ASRock X299 Taichi and has proven to be beneficial as installing a network card leads to extra costs. 

Another similarity between the Killer SLI/ac and the Taichi is the inclusion of five four-pin fan headers, each outputting a minimum of 1A.

The Killer SLI/ac has four DDR4 DIMM slots with a maximum capacity of 64GB, which is standard for the four-slot design.

The board consists of eight USB 3.0 ports, two of them being USB 3.1 that support both Type A and C.

The Killer SLI/ac gives you more than your money’s worth with six SATA3 ports allowing for future expansion, and two M.2 slots that support PCIe Ultra.

Audio

Despite the outdated Realtek ALC 892 audio codec the motherboard uses, it is important to note that this board has a 7.1 analog and optical array port on the rear I/O (input/output).

It also supports Blue Ray and high-definition audio playback connectors, meaning the hardware is up-to-date with modern audio standards.

Gaming

The Killer SLI/ac is perfect for gamers as it is part of the SLI brand of motherboards which allow the use of two graphics cards. 

This board benefits over the more gaming-focused ASRock motherboards such as the Asrock fatal1ty z97 killer.

These benefits include an extra 32GB of RAM capacity,  extra SATA and M.2 ports, and wireless LAN integration.

Presentation

ASRock has chosen to go with an eye-catching black and white design. Hints of silver on the heatsinks and PCIe slots combined with the coloring make choosing a theme for your rig easy.

The heatsinks are made from aluminum alloy which lowers the temperature of the MOSFETs to prevent overheating.

RGB Headers and Software

Speaking of colors, ASRock yet again makes use of RGB headers through its Polychrome software.

Unlike the ASRock X299 Taichi, the X370 Killer allows you to change the color of individual headers.

BIOS and Overclocking

BIOS is easily accessible and has standard Option and Feature Control menus. It also has an OC tweaker menu that the b-series of ASRock Motherboards lacks.

The OC tweaker tab is where all of the overclocking and system tuning occurs. It allows you to change the frequency and voltage of the core processor, and provides options for loading XMP and altering the DRAM settings.

Before deciding if the ASRock X370 Killer SLI/ac is the motherboard for you, let’s go over some pros and cons.

  • Affordable
  • Built-in 802.11ac WIFI

Common Questions about ASRock X370 Killer SLI/ac

What is the power rating of the ASRock X370 Killer SLI/ac?

The ASRock X370 Killer SLI/ac boasts a twelve-phase power design with premium 45A chokes.

This is an improvement from the other x-series models such as the ASRock X570 Pro4 as those boards consisted of a ten-phase power design.

It allows you to dabble in overclocking, running at a stable 4GHZ.

What makes the Steel PCIe Slot advanced?

The main reason for the PCIe slot on the ASRock X370 Killer SLI/ac being steel is to increase its rigidity.

Not only does this make it sturdier, it decreases the potential of unwanted signals causing any interference.

What is included in the box?

Fresh out of the box, you will receive two SATA cables, two screws for the M.2 modules, one I/O Shield, one ASROCK SLI 2-way High Bandwidth Bridge, two WIFI antennas, a Software setup and installation guide, a driver CD, a guide to install memory modules, and a postcard.

The packaging of the motherboard is similar to z-series boards like the ASRock Z370 Killer SLI/ac.

Customer Reviews

“After I updated the BIOS, the RAM speed was where it needed to be. The inclusion of the five 4-pin fan headers and being able to easily control the chassis fans is an excellent function. Upon discovery, I found that the board can completely switch off the fans, making my PC extremely quiet. Using the two PS/2 ports, it was possible to use a DVD to install Windows 7. Overall, I am pleased with the permanence of my machine and the board. This is a board that I can recommend.”

5/5 Stars

“I had no problems with this board initially, but eventually one of the PCIE slots on the board caused my PC to crash multiple times and the board to stop functioning. However, this was most likely due to my GPU occupying a space in one of those slots. But despite my troubles, this motherboard is worth your pennies. Not only does it have integrated Wifi, but it supplies me with all the features I could ask for.”
